Cooper, who played the last of his 70 Tests in 2017 against Italy, returned to the international fold last month. And the 33-year-old was his side’s hero, finishing with 23 points.
Cooper held his nerve to strike the ball sweetly from 40 metres out on an angle after scrum half Nic White poached the ball from the last scrum in a nerve-wracking finish.
Andrew Kellaway had scored the Wallabies’ only try on 17 minutes but Cooper’s boot kept them in contention.
The Springboks scored all three of their tries from line-out drives with Malcolm Marx grabbing two and the other coming from Bongi Mbonambi. (BBC)
